OPTICAL FIBER FOR OPTICAL AMPLIFIER AND MANUFACTURING METHOD THEREOF |
摘要 |
PURPOSE: An optical fiber for an optical amplifier and a manufacturing method thereof are provided to reduce the manufacturing cost by doping a core layer with a mixed solution of rare earth and metal ions using a solution doping method. CONSTITUTION: In order to manufacture an optical fiber using MCVD(Modified Chemical Vapor Deposition), a clad layer and a second core layer are formed in a silica substrate tube(S10). A first core layer is formed on an inner surface of the second core layer(S20). The first core layer forms a partially-sintered layer that provides a host with respect to a Tm¬3+ ion and a metal ion. A mixed solution of the Tm¬3+ and metal ions is uniformly doped on the first core layer(S30). After completing the doping of the mixed solution, an optical fiber is manufactured by wire-drawing a glass rod containing the Tm¬3+ and metal ions(S40).
